  • Extends the life of key conveyor components
  • Reduces wear from abrasive materials
  • Prevents belt slippage by increasing the coefficient of friction between the conveyor belt and the pulley
  • Creates a self-cleaning action on the pulley surface and prevents the buildup of transported bulk material, water, snow or ice


Most often, lagging is attached to the pulley via Pulley vulcanizing (preferred in heavy-duty applications). Or, replaceable lagging can be used. The lagging strips are bolted or welded to the face of the pulley and can be easily replaced in the field. Ceramic pulley lagging is constructed from hundreds of individual ceramic tiles molded into a durable rubber backing. In certain applications, ceramic lagging can significantly increase drive traction.


Plain steel drum pulleys (with no lagging) are best in dry, clean environments where traction is not critical, and when no foreign material is present on the return belt. Drum pulleys with plain rubber lagging are typically used in snub applications where traction is not critical. Drive pulleys that operate in wet or damp conditions are commonly grooved and are available in a smooth, herringbone or diamond design. Ceramic lagged pulleys are used in applications with abrasive material on the return side of conveyor belt.
